Gall mite on a pear: causes and measures to combat chemical and folk remedies

The appearance of spots on the leaves of a plant signals a serious problem to the gardener. It is urgent to take preventive measures in order to prevent the spread of the outbreak and not be left without a crop. Such a danger is represented by a gall mite that appeared on a pear. It feeds on the juices of the tree, weakening and depleting the latter. The harvest is meager and low-grade. It is urgent to get rid of the pest and prevent its further appearance on the site.

Description of the pest

The gall mite that lives on a pear belongs to a sucking insect species.It cannot be seen with the naked eye, since the body of the pest reaches a maximum size of 0.3 mm. With the help of a sharp proboscis, he perforates the leaf and sucks the cell juices out of it. The tick can live everywhere where pears are grown.

In winter, tick larvae hide under the scales of leafy buds, and with the onset of heat, they suck out the juice from them, as a result of which the bud dies. In the same period, the females lay eggs, and the larvae that have grown from them continue to suck the juice from the tree. 3-5 new generations of ticks grow in one season.

Reasons for appearance

The gall mite spreads under the influence of human factors, with the help of insects and birds, as well as wind, which contributes to the appearance of pest larvae. It can be provoked by a thickened crown, a long absence of sanitary pruning, as well as an excess of fertilizers containing phosphorus in the soil.

Some stimulant drugs used in horticulture can increase the number of gall mites. In addition, insecticides, actively used recently, destroy the natural enemies of a dangerous pest. Diseases also greatly weaken the pear, making it available for the reproduction of pathogenic organisms.

What harm is a tick?

The gall mite can cause significant harm to a he althy pear, which is expressed as follows:

• slowing the growth of young shoots;
• kidney destruction;
• spoilage of buds and ovaries;
• significant decline in yields.

A pear affected by a gall mite is deficient in nutrients, as a result of which it may not endure the winter and freeze out in severe cold.

Measures against gall mites

Prevention of gall mites in the garden is to follow simple agricultural practices. However, if the pest is already mastering your favorite pear varieties, you need to act immediately.

Chemical treatment

Chemical methods of dealing with gall mites bring the fastest results. In addition, they are recognized as the most efficient and effective.

Apollo

Apollo is a contact pesticide. Able to completely destroy pests without harming the beneficial fauna of the garden. A feature of the drug is that after treatment, not only adults die, but also young animals, as well as eggs laid by females. Processing is carried out in accordance with the instructions attached to the tool.

Karate

Karate drug destroys not only female gall mites, but also their eggs. It is not recommended to use it if there is an apiary nearby. The active ingredient simultaneously destroys many other garden pests and their larvae.

Fufanon

Pesticide contact intestinal action. Its basis is an organophosphorus compound. In addition to the gall mite, it helps to get rid of other pathogenic microorganisms. It is recommended to use if insects have become immune to pyrethroids.

Biological pesticides

Proponents of organic farming in the fight against gall mites on pears often prefer biological pesticides, considering them to be environmentally friendly.

Vertimek

This drug contains a biological pesticide obtained by processing the waste products of fungi. Refers to the means of contact intestinal exposure. Use "Vertimek" if the gall mite living on a pear has shown resistance to other acaricides. The active substance does not act through cell membranes, therefore it does not have the ability to accumulate in fruits.The effectiveness of the drug improves with increasing ambient temperature.

Fitoverm

When gall mites appear on trees, effective control by spraying with pesticides is carried out before bud break or immediately after flowering is completed. During the period of the first spraying, the pest females that spent the winter in the buds of the tree are destroyed. For this purpose, Fitoverm is well suited. As a result of its impact, it is possible to avoid a wave of mass reproduction of insects in the spring.

Rules for the preparation of folk remedies

To fight the invasion of gall mites on a pear, folk remedies based on natural ingredients help. An infusion of dandelions has proven itself well, which is prepared as follows. Take 1 kg of fresh dandelion leaves, pour 3 liters of water and leave to infuse in a dark place for 3 days.The resulting infusion is filtered, a little liquid soap is added and the pear is sprayed with it.

To get rid of the gall mite, an infusion of calendula herb is prepared. They take 100 grams of flowers and boil them in 1 liter of water for 5 minutes, after which they insist in a dark room for 5 days. After that, the infusion is filtered, diluted with water in a ratio of 1: 1 and the pear is sprayed.

An excellent result in the fight against gall mite shows an infusion of potato tops. It is prepared from 1 kg of fresh or 0.5 kg of dried chopped tops, which is poured into 10 liters of warm water and allowed to infuse for 4 hours, after which it is filtered, a little liquid soap is added and the pear is processed.

You can use the prepared infusion only for a day, after which it becomes unusable.

Processing of pears against gall mites is carried out in the morning or evening hours, as well as in dry cloudy weather.Under the rays of the scorching sun, droplets of liquid can cause burns on the leaves. In addition, some active ingredients lose their effectiveness under the scorching sun.

Prevention

Preventive measures aimed at combating the gall mite on pears are aimed at not creating favorable conditions for the reproduction of the pest. It is necessary to correctly and accurately calculate the dosages of the applied dressings, especially those containing phosphorus.

It is definitely worth carrying out sanitary pruning of trees, removing dead bark, removing leaves with the onset of autumn and digging up the soil in the near-stem circle of the pear. Timely whitewashing of the trunks with a solution of lime also prevents the appearance of gall mites in the garden.

Growing weeds should be either completely removed from the site or mowed. In the latter case, the roots remaining in the ground will replenish the supply of nutrients. Treatment with chemical and biological agents, as well as folk remedies intended for the destruction of gall mites, is also recommended for prevention purposes.Its frequency is 1 time per month.

A good result in the prevention of pests on pears shows the use of trapping belts, for the manufacture of which burlap or corrugated paper is used.
